FIG. 5 in An updated checklist and a DNA barcode library for the earthworms (Crassiclitellata, Oligochaeta) of Corsica, France

FIG. 5. — Observed and estimated species diversity of earthworms in the island of Corsica: A, incidence-based rarefaction and extrapolation curves of species numbers;B, Chao asymptotic estimator of species numbers. The figure compares the results obtained when considering all species-level lineages obtained with DNA barcodes (All), when considering non-cryptic lineages only (NC) and when considering all endemic lineages (End). Solid lines represent rarefaction curves, whereas dashed lines represent extrapolation curves; shaded areas are 95% and error bars confidence intervals based on a bootstrap with 200 replications.
